...hence the thread!!!

has anyone mentioned that it could be the emmersed leaves dieing back to make way for new, submerged leaves?

This is what happens with most plants when you have just bought them, i would give it a few weeks before you can see any "real" problems.

^Why such a convoluted lighting schedule? Just interested 'tis all.

Depends on what you mean by thrive. You don't need high lighting for plants to thrive. In fact I believe it is easier to keep plants at the lower end of the lighting scale, no need therefore for all this constant daily fert dosing and infinite complexities associated with CO2 injection....

The fact that the CO2 appears to me to be unstable is in my mind is the root of the algae problems perhaps. Plant deficiencies cause by fert dosing problems another (perhaps unrelated) problem too.

Tank needs to settle, to get to a balance. In the meantime, I'd be tempted to reset the environment...reduce the growth stimualtors, beginning of corse with light, & drop back the CO2 & dosing riegeme. Then GRADUALLY increase the lighting... CO2 & ferts to match, to reach that EI stable tank....

Okay how many hours do you have your lighting on?
Even on low light.

On at 11am, off at 8pm.

My thinking for this was that plants have evolved to use sunlight periods, which I guessed average out at about 9hrs in more tropical regions. At least that's how I think I thought of it about 1.5 years ago when I set the timer.
